About chargeMOD chargeMOD is an energy-tech company building India's EV charging ecosystem end to end: charger hardware, power electronics, control and communication, and the software and app that run the network.

Our network spans thousands of charge points across India, Nepal and Dubai, and we have delivered projects with partners such as KSEBL, Kochi Metro Rail, L&T;, the Murugappa Group and Ather Energy.

Key responsibilities

- Design and develop power conversion stages for EV: AC-DC (PFC) front ends and isolated DC-DC converters (LLC, phase-shifted full bridge, DAB).
- Simulate circuits and control loops in LTspice, PLECS, PSIM or MATLAB/Simulink before building hardware.
- Select and size power components: MOSFETs, IGBTs, SiC devices, gate drivers, capacitors, sensors and protection devices.
- Design and test magnetics (inductors and high-frequency transformers) with suppliers.
- Create schematics and review PCB layouts for power paths, thermal performance and EMI.
- Build and bring up prototypes; measure efficiency, ripple, transient response and thermal behaviour in the lab.
- Work with the firmware team on control, protection and fault handling (over-voltage, over-current, over-temperature, ground fault).
- Support compliance and certification testing (IS 17017, IEC 61851, EMC and safety standards).
- Debug field returns and production issues, and feed fixes back into the design.
- Prepare design documents, test reports and BOMs.

Required qualifications

- B.E./B.Tech or M.E./M.Tech in Electrical, Electrical & Electronics, Electronics, Power Electronics or a related field.




- 0–3 years of experience in power electronics design, testing or validation. Freshers with strong academic projects or internships are encouraged to apply.
- Solid fundamentals in converter topologies (buck, boost, flyback, full bridge), switching devices and basic control theory.
- Hands-on lab skills with oscilloscopes, differential and current probes, power analysers, DC power supplies and electronic loads.
- Comfortable working safely with high-voltage, high-power hardware.
- Ability to read and create schematics in at least one EDA tool (Altium, KiCad, OrCAD or similar).
- Clear written and verbal communication in English.

Freshers: please share your final-year project, internship work or any hardware you have built, with photos, reports or a GitHub link.

Nice to have

- Experience with EV & EV chargers, onboard chargers, solar inverters, UPS, motor drives or SMPS products.
- Exposure to SiC/GaN devices and high-frequency magnetics design.
- Digital control on microcontrollers or DSPs (TI C2000, STM32 or similar).
- Knowledge of EV charging standards and protocols: IS 17017, IEC 61851, CCS2, Bharat AC/DC, OCPP.
- Thermal design and EMI/EMC debugging experience.
- Familiarity with design for manufacturing and working with contract manufacturers.

What we offer

- Hands-on work across the full product cycle, from simulation to certification and field deployment.
- Mentorship from senior hardware engineers and a well-equipped power electronics lab.
- A rapid-moving startup culture with room to grow into senior and lead roles.
- Competitive salary, health insurance and performance-linked rewards.
